As an IT supplier, you're well versed in the technicalities of pervasive working. A friend of this column bossed a notorious networking distributor in Farnborough and most of the time he was all over the place!
But now a personal productivity invention could prove a godsend to all you mobile professionals. (Although not our friend Duncan, as he's out of the business now.)
This time saving lifesaver is an application called UbiCabs, that its makers claim will improves the supply of transport to mobile professionals. It achieves this by fine tuning the supply chain of taxis and mini cabs, helping drivers and potential clients find each other more readily.
It's the brain child of by Lorenzo Caffari, who was head of IT in the logistics division of Carrefour, the world's second biggest retail chain.
He used his logistics experience and combined it with the GPS part of mobile technology so that customers and taxi driver can track each other on screen.
Both sides will save money and increase productivity. The drivers spend less time burning diesel while they run an empty cab, while passengers spend less time trudging the street, forlornly trying to get a lift off a psychopath who they've mistaken for a cabbie.
This isn't just a money saver. It's healing the divide between north and south London.
